Abstract

A security system for a mobile piece of equipment, e.g. vehicle, that may be stolen consists of a central processing unit (in the equipment) in data communication with component control units CCU attached to respective parts of the equipment being protected. The control units accept a code from the memory of e.g. a vehicle ignition key, alter the code, and transmit the altered code back to the CPU for checking to control disabling of the equipment (vehicle). These systems in turn may be linked to a central database via a system control center SSC to control the inventory and regulation of parts both within each vehicle and between all vehicles protected by the system. <IMAGE>

22 5l S i-j3 MULTI-ELEMENT SECURITY f2Y5JEMS

Background of the Invention

This application is a continuation-in-part of U.S.

Serial No. 392,092, filed August 10, 1989, the contents of which are h-ereby incorporated by reference.

Theft and unauthorized use of mobile pieces of equip ment such as motor vehicles, construction equipment, aircraft and the like, is widespread. Although numerous attempts in the past have been utilized to curtail such theft and unauthorized use, they have generally met with limited success. Accordingly, there has been a long felt need in the art for a security system which provides an efficient deterrent to such crimes.

The security systems presently available do not provide an efficient deterrent to theft of component parts. Alarm systems such as horns, beepers or sirens have little effect in deterring thieves. In urban areas especially, the 20presence of sirens and alarms has become so common as to be ineffective. Radio signaling systems are likewise ineffec-_ tive because they rely on the speed and efficiency of the local police departments. Today, many police departments are understaffed and unable to apprehend a thief before the radio signaling system can be disabled. A proliferation of such a system can only exacerbate the problem.

:I- Although anti-theft systems which utilize an electronic key to secure a motor vehicle have been described in the past, none have provided an effective means of protection. One such security system is described in U. S. Patent No. 4,192,400, issued to John A. McEwan on March 11, 1980. McEwan discloses a key which contains a shift register that when inserted into the motor vehicle causes an plectronic clock to redial the data stored in the shift register. A - comparison device then compares that data with data previous10 ly stored in the vehicle. If a match is found, the vehicle is usable. However, if the data does not match, the distributor or starter motor of the vehicle is disabled.

U-S. Patent No. 4,642,631, issued to Stanley C. Rak on February 10, 1987, describes an interactive security system in which a first circuit produces a control signal, and a second circuit produces a code word representative of a sequence of logic states, with the logic states sequence being a function of the control signal- A comparison circuit compares the signals produced to a predetermined stored signal, and if an match is found, access to a vehicle or other device is provided.

Similar security systems are described in U.S. Patent Nos. 4,300,057, 4, 370,561, 4,383,242, 4,538,135, 4,672,224 and 4,676,082.

The above described security systems have several disadvantages- For example, all such security systems can be destroyed and the mobile equipment can be transported to a - 1 - remote location, repaired and resold. Alternatively, the mobile equipment can be dismantled and the various Parts sold separately. It is also well known that, body parts i.e. trunk lids, hoods front fenders, as well as viable subsystems such as radios, recording devices, audio telephones, or other electronic devices, may be completely unprotected by a particular security system, and thus, can be removed and resold.

Lastly, through the use of a central data base, changes in registration, replacement of parts, major repairs, acci dents, as well as a vehicle's complete service record may be recorded. It is the purpose of this system to render the vehicle and its components worthless for resale and unmar ketable by unauthorized persons. The data base account s for every Protected part of the entire production of a particular modei type motor vehicle. If a particular protected part, such as a left front fender, is removed from one vehicle and installed in another, neither vehicle would operate. The removed part could not be placed in any vehicle in the entire Production run, rendering it worthless to the unauthorized user. This provides the additional advantage of enabling compilation of marketing and quality assurance information that can be used by a dealer or manufacturer. In summary, the subject invention provides not only a security system, 25but also a comprehensive system for planned maintenance of a vehicle and its parts, as well as an accurate inventory mechanism and marketing information.

SummarX of the Invention The subject invention provides a security system for a mobile _piece of equipment which comprises a component control unit (CCU), a central processing unit (CPU), a system control center (SCC), and an international cont-rol database (IDE3). The CCU, and the CPU reside in the protected vehicle, the SCC resides at the authorized dealer/agent premises and the IBT resides with the manufaturer, but all are essential to the operation of the system- There are two types of CCUs: 1) passive, is associated with a selected component of, a piece of equipment. The CCU has means for receiving and storing data which has been entered during the manufacturing process, and by the SCC which can be entered by (the authorized dealer/agent or by the factory database. The factory code,(FAC), may not be changed during the lifetime of the protected part. It can not be read by the SCC as it is under control of the operating system which also controls the factory data base. 2) active, having the same memory capability as the passive CCU, addi- 20tionally being able to disable the part it protects. The CPU receives data from the ignition key and sends it to the CCUs which alter the data received, transmitting the altered data back to the CPU.

The CPU is located within the mobile piece of equipment 25and has means for polling each of the component control units in Proper sequence, and means for verifying codes or altered codes received from the component control unit- If there are - q- codes that are incorrect, out of sequence, or missing, the CPU will instruct the active CCUs to disable their parts. The SCC is capable of entering data in the memory of the CPU and relating such information to a central database. 5 The IDS is capable of correlating and keeping an i nventory of information received from the SCC: such as authorizing code changes in the CPUs and CCus memory. The IDS can read both the ROM and EProm memory of the CCUs whereas the SCC's &ccess is limited to the EPROM.

1 Detailed Description of the Invention

The subject applicatiQn uses the term 'vehicle" in describing the subject invention. However, the term "vehicle" is not intended to limit the invention to vehicles per se., but rather the invention is applicable to all mobile pieces of equipment.

The subject invention comprises three major systems, each having numerous subsystems- The three major systems 10 are: (1) the vehicle disabling system, (2) the Dealer/Agent equipment 1 an protected component (3) the central data base.

The vehicle disabling system is comprised of one or More component control units (CCU) and a central processing unit (CPU) which communicate with each other. Typically, the system comprises multiple CCUS. Some are passive and others active that are installed at inaccessible locations within a All CCUs contain a memory for storing data that can be accessed by the CPU. one function of the CPU is to verify signature codes and sequence of coded pro- tected parts. CPU commands to active CCUs can disable the part or system to which they are attached. The CPU would send such a command if after the polling function one or more signature codes are incorrect, missing or out of sequence.

Autosafe can determine if protected parts are discon nected from the system- If a protected part is disconnected, the vehicle will not operate until approval is received from - -I- the data base. In the event the protected part becomes disconnected accidentally, the system has a manual override, activated by a code from a' keypad in the vehicle that allows a predetermined number of starts. This Procedure allows the vehicle to operate until it is returned to an authorized dealer/agent for code refreshing.

The CPU communicates with each protected component over the vehicle wiring system or other means. CPUs transmit data received from the ignition key memory to a CCU which alters the data and transmits it back to the CPU. ' If data received by the CPU during the polling routine matches the data stored in the memory of the CPU, vehicle components are enabled- (Enabled means that active components are allowed to function for the operation of the vehicle.) If data sent to the CPU memory does not match what is stored, the CPU sends a command to active CCUs that disable the component and the vehicle.

The Dealer/Agent (DA) equipment interface between the data base and the vehicle is the System Control Center (SCC), which is operated and owned by DAs also provides the communi- cations link between the vehicle CPU and the central data- T n base. The DA typically will own one to five SCCs.

addition to being the communication link between the central database and the vehicle, the SCC provides an important security element to the integrity of the data base. Important events such as resale, accidental damage, maintenance, repair, etc., are recorded in the database and can be re- - g- trieved by any authorized DA anywhere in the world. SCC equipment allow Protected Parts to be replaced in any country -With authorized DAs. To replace a protected part, its code is entered by the database into the CPU memory.

The third major portion of the system is the International Data Base (IDS) must approve any component changes within the vehicle. IDS maintains an inventory of each protected component in vehicles, parts in dealer's stock, and factory inventory.

The IDS logically binds every 'protected vehicle (includiins each of its Protected components) of particular models and model years together. A signature code (SC) address is created for each protected component of every vehicle with the Autosafe system manufactured worldwideConsequently, there can be no resale markeL for stolen vehicles and components covered by the system. If not authorized by the central database, a protected part having the wrong signature code or no SC will not function nor allow the vehicle in which it is installed to function. The IDS also provides software programs necessary to maintain security integrity of the system.

The above description is a basic overview of the major systems in the subject invention. The three types of disa 25 bling schemes capable of being incorporated into the VD5 will now be addressed. They are: active, logic, and passive.

In a active disabling device, components are disabled - Ok - by embedding a triac or other electronic switching device within the windings of an electrical motor, alternator, or relay or in a spool of a solenoid coil that controls either a vacuum or hydraulic flow. Active ref ers to a CCU which controls a devise performing an affirmative action such as blocking or disabling a component. Components such as the fuel injection system and transmission can be protected using an active mode disabling scheme.

An example of a logic disabling scheme would be a disruptive message send to a processor that is already controlling a component such as a distributor- Passive disabling devices typically incorporate a CCU that becomes inoperative if the component to which the CCU is attached becomes damaged. passive disabling devices are useful for components such as bumpers, fenders and trunk lids. In a passive disabling device, a %CCU is typically incorporated into large rectangular piece of a material which is affixed to the protected component and cannot be removed without destroying the CCU's electronics. For example, the protected component may be mounted upon a pad, which if damaged, will cause the CCU to indicate a problem and disable: the system. Even if the would be thief knew the location of the pad and carefully cut around it, repair of the protected component would not be economically feasible.

The subject invention contemplates ineans to reactivate equipment components which have been disabled by commands from the CPU. For example, if a particular protected comPo- -to- nent is disabled by switching means, reactivation can be achieved by commands from the CPU. Unauthorized repair can be made difficult or impossible by, for example, encasing the protected component within a case requiring specialized tools to open. Another alternative is to equip a protected component with an electronic circuit that can be enabled or disabled by entering a unique digital code at a remote keypad. Other alternatives are, of course, also possible.

Roadside service can be accommodated by the subject system. 10 By using a portable laptop SCC and cellular telephones, roadside service and reprogrammins of the CPU to accommodate replacement parts may be accomplished. Request for database changes from a portable SCC are performed in a similar manner to that described for stationary units wilth the added precau- it tion of usino codes and encrypted language to eliminate the possibility of radio or wire transmission interception by unauthorized parties. Components which have been disabled by commands from the CPU can be reactivated by either a portable or a stationery SCC. For example, if a protected c9mponent is in need of a replacement because of malfunction, a new replacement part may be drawn from stock. This part already. has a factory key code and a dealer code impressed on it. Both codes would be recognizable as replacement parts rather than a part in the assembled vehicle. The part i- s removed from the replacement part inventory of the central database and is added to the active part inventory for the vehicle in which the part is installed.

The central database will not allow a Part to be added to the active vehicle part list unless a similar part is taken from a factory/dealer replacement part list. Likewise. a part cannot be taken from the factory/dealer replacement is subz7acted from a part 14sz until a defective similar part s wl In the vehicle part list. By cross-checking all par?;-h.

7 invention- [I- p 1 Should the vehicle's power be interrupted, the system is disabled. When power is returned, a touch pad is keyed with the - - --op erator 's code, and the key is turned to the on position. The system will then be restored to operation.

The first sequential CCU is an electronic key that opens access doors and starts the engine. The key functions to interrupt the CPU and causes the CPU to transmit a code request back to itStored within the ignition key, in its memory, are three key access codes one from the factory, one from the dealer, and one from the Customer. The system is versatile so that if the dealer has not yet sold the vehicle, a special dealer code may be used allowing the veh-ic-le to be started a Predetermined numiber of L-5mes. When the key receives the message from the CPU, the logic gate having been changed by the three key codes, then changes the message and sends it back to the CPU. This handshaking' procedure activates the CPU- The ignition key utilized by the operator contains memory (factory code (FAC) key and customer code (CC), and line drivers in its handle which can mechanically and/ or logically open access doors- As the key is turned in the cylinder of the ignition locking system, it is powered sending an interrupt to the CPU.

The FAC crosschecked for duplication and stored, at the time the protected component is manufactured, in the central database. One Preferred code is a 16 digit (hexadecimal) code number.

The figures depict a Most preferred embodiment of the subject inventionFigure 1 shows various components of the subject invention utilized in a motor vehicle. The CPU (1) receives the CC from the ignition key memory and transmits the CC message to each protected component, which in turn is altered by the CCU as it passes the logic gate which is controlled by the DAC and is trans5 mitted back to the CPU for verification. The CPU 'polls' each protected component of the vehicle as the key i.,; turned in its cylinder. Polling results in a central processor verifying that each protected component has been yroperly authorized to be included with the vehicle being protected. If all protected components 10 pass inspection, the system powers down until 'the polling sequence When. access to the vehicle --.s required by the operator, an elecltr-.7c ignit-lon key (2), is inserted into the -locking receptacle not shown). insertion of the Jignit-lon key causes the CPU to poll including, for example the key (2), key the protected components receptacle (3), distributor (4), electric -fuel injectors (5), crank shaft (6), and starter (7).

I-- is understood that the components described as being Protected components herein are exemplary only, and that protected comiponents in any particular piece of mobile equipment are chosen at the manufacturer's discretion- Such protected components can include electronic systems such as automobile body parts, stereos-, telephones. communication systems, navigational equipment. and th alike.

The agent key module "includes memory and a communication port programmable from the SCC at the agent's place of business.

-1q- J1 i The agent key can be programmed to operate any particular vehicle; to allow any number of starts.

Figure 2C shows a detailed representation of one type of electronic key (2). mechanical lock cylinder (3) and intelligent interface. More particularly, the key (2) includes an extended portion (10) in which is arranged a plurality of members (11) designed to accomplish electrical contact within receptacle (3) when the key is turned. Key receptacle (3) contains a plurality of terminals (12). such as a coded input terminal, a first and second coded output terminal, a positive voltage (8+) terminal, and ground terf- ai na 1 it is understood that the CPU of the inventive system recognizes whether the key has beer, inserted iint%o the ignition or,nzo an access door of a mobIle piece 07 equipment -by recognition ol' a control signal comin<__ from either the first coded output 15(ignition). or the second coded output (access door) in the key receptacle. Such asignal could be generated, for example, by appropriate logic circuitry incorporated into the key (2) and applied to the coded input terminal, or generated by circuitry incorporated into the key receptacle (3)_ Appropriate mechanical and/or electronic means can be pro vided in response to the first and second coded output to operate door latches and/or energize the ignition system of the vehicle.

in the art and will not be further del Such means are well known scribed.

Figure 2A shows a detailed representation of a second type of electronic key (2), The key includes an extended portion which is made of the same material and is fitted with key slots to actu- -Is- ate cylinder tumblers as in any mechanical locking system. Co n tacts (A&B) are positioned to provide electrical contact with a -_-receptacle which passes a serial data stream containing the coded rnessages sent and received by the CPV.

The key of figure 2A is operated by turning 50" clockwise after insertion. This permits the key to come in contact with two conductors positioned in line with the lock cylinder so that the CPU can poll-the memory in the key. The extended portion the ignition key is a mechanical key capable of operating other locks in the vehicle- Figure 23 shows a modified lock cylinder that links the CPU to a Ney such as depicted in Figure 2A- An existing lock cylinder is utilized by modifying the key cap to allow the contacts (A & a) on the key (2) to be electrically connected to the CPU via tI-Ie modified cylinder. As depicted, the cylinder housing has been modified by the addition of a power pire from the CPU and a ground wireOther modifications include an added Slip Ting Stator mount, and added slip ring stator, and an added slip rIng slider which function to ensure alignatent of the contacts on the key and hous- ing- Figure 3 shows a vehicle crankshaft permanently coded with an optically reflective material (19). Although this figure illustrates the optically reflective material on the crankshaft, such a system is adaptable to any moving part. This component is verified by the CPU with a command to controller (21) (see figure 4] that generates beams of light (14, 16) illuminating the coded reflective strip (19)- The reflective coding strip (19) of the crankshaft alters the code returned to the CPU via a light sensitive reading device (20-)_.' As the CPU recognizes the altered code, it verifies that the crankshaft is native to the vehicle. Components (15) and (17) are 5 optical transmitters and receivers respectfully, while component (18) is a frame that stabilizes the various optical components. it is understood that this light reflective scheme is an example of a communication link, and other communication links to transmit information between moving parts may be incorporated in the subject 10 invention.

Figure 5 shows a block diagram depicting interrelationship of the various components of the subject invention and their relationship to each other. F in a circle represents the actory code and C represents the customer code. The CPU receives the CC data from the ignition key and sends the CC to each component which then alters the code in accordance with the instructions contained in reply signal which reflects this alteration.
